Gemini CLI Skills

A radical simplicity skill that strips AI coding assistants back to first principles. Caveman enforces brutally simple code — no abstractions, no frameworks, no clever tricks. Just plain, readable, maintainable code that any developer can understand at a glance. Inspired by the philosophy that the best code is the code you don't write.

The best agent harness — a universal TUI orchestration framework supporting Claude, Gemini, OpenAI, and more. Previously known as oh-my-opencode, it provides a unified terminal interface for managing multiple AI agents with smart routing and session management.

A lightweight meta-prompt framework specifically designed to solve 'context rot' in AI coding sessions. GSD uses Spec-Driven Development, multi-agent orchestration, and atomic task decomposition to maintain Claude's output quality across long sessions. Widely adopted by engineers at Amazon, Google, and Shopify. Addresses the core reliability problem of AI coding assistants on complex, multi-session projects.

Pre-indexed code knowledge graph for Claude Code, Codex, Cursor, Gemini, and other AI agents. Instead of repeatedly grepping and reading files, CodeGraph parses your codebase once into a structured map of functions, classes, imports, and call relationships — so agents navigate with fewer tool calls and far less token spend. Supports 19+ languages, works 100% locally, integrates via CLI, MCP, or Agent Skill.

The largest curated skills directory on GitHub, maintained by the Composio team. 1,000+ production-ready Claude Skills and Plugins organized by use case — from coding and DevOps to marketing, design, and research. Compatible not just with Claude Code but also OpenAI Codex, Cursor, Gemini CLI, and Antigravity. Each skill includes install commands, compatibility tags, and real-world usage examples. The go-to reference when you need to find a skill for a specific task.

A comprehensive collection of AI coding guidelines curated from Andrej Karpathy's public writings, talks, and social media posts. Distills the legendary AI researcher's hard-won wisdom on building reliable AI systems, debugging neural networks, and writing clean ML code into an actionable skill for Claude Code and other AI assistants.

A curated collection of 1000+ agent skills from official dev teams and the community, compatible with Claude Code, Codex, Gemini CLI, Cursor, and more. The most comprehensive open-source directory of agent skills organized by category and use case.

A research-focused AI agent skill collection with 170+ plug-and-play tools covering bioinformatics, drug discovery, chemistry, medicine, earth science, and financial analysis. Provides access to 250+ specialized databases and 60+ optimized Python packages. Compatible with Claude Code, Cursor, Gemini CLI, and any tool supporting the Agent Skills standard. Built for scientists and researchers who need AI assistance with domain-specific workflows.

A persistent memory plugin for Claude Code that automatically captures everything during coding sessions, compresses it with AI, and injects relevant context back into future sessions. Supports ChromaDB vector search, progressive disclosure, and multi-provider AI compression.
